The effects of Fe(III) reduction on biodegradation of fuel oxygenates and chlorinated ethenes
… contaminants prevalent in groundwater systems. Fe(III) reducing conditions are dominant in many sedimentary environments. However, the effects of Fe(III) reduction on biotransformation of MTBE/TBA and chlorinated ethenes are not well understood. This research investigated the biodegradation of …

Arsenic mobilization through bioreduction of iron oxide nanoparticles
Arsenic sorbs strongly to the surfaces of Fe(III) (hydr)oxides. Under aerobic conditions, oxygen acts as the terminal electron acceptor in microbial respiration and Fe(III) (hydr)oxides are highly insoluble, thus arsenic remains associated with Fe(III) (hydr)oxide phases. However, under anaerobic …

The Ferrous Regeneration Process for Use in Alternate Anode Reaction Technology in Copper Hydrometallurgy
The Fe(II) regeneration process is an important aspect of Alternate Anode Reaction Technology (AART) using Fe(II)/Fe(III)-SO2 reactions for copper hydrometallurgy; however little has been done to study it specifically. The process regenerates Fe(II) via Fe(III) reduction by SO2(aq), catalyzed by …

Iron reduction mediated increases in carbon oxidation and phosphorus precipitation in on-site wastewater systems
1.2 billion people lack access to safe drinking water, 2.6 billion have little or no sanitation, and millions of people die annually from diseases transmitted through unsafe water and human excreta. Onsite wastewater systems (OWSs), referred to as septic tanks, serve approximately 25% of the United …

Anaerobic Dissipation of Herbicides in Microbiologically Induced Soil Redox Regimes
… Particular emphasis was placed on the effects of redox conditions and corresponding anaerobic microbial processes on herbicide mineralization and bound residue formation as routes of dissipation. Herbicide fate was evaluated by quantifying the distribution of radiolabeled material in the …

Influence of Iron Speciation on Redox Cycling and Reactivity With Persistent Organic Contaminants
In this study, FeII/FeIII complexes with low molecular weight organic ligands were used as surrogate models for studying iron-mediated redox processes. Initially, the redox reactivity of Fe II-organic ligand complexes with nitro-organic explosives was investigated. Ligand-screening experiments …
